Birther candidate on the air in N.H.

A little-known presidential hopeful who's the self-described "king of the birthers" is the first to go up with a TV ad in New Hampshire.

Andy Martin is on the air a year before the Granite State primary with a 30-second spot that continues his questioning of President Barack Obama's citizenship. The ad starts airing today on WMUR, NHJournal reports.

"One hundred million Americans have doubts about Obama's origins," Martin says in the ad.

“The ad is going to initiate a process of undermining and delegitimizing Barack Obama that could possibly bring Hillary Clinton back into presidential politics," he said in a statement.

Martin has said he believes Obama was born in Hawaii, but that the White House is blocking the release of Obama's birth certificate because it could include embarrassing information.
